Lebanon murder suspect says he suffered long history of physical, sexual abuse at the hands of his father

Shortly after a man was stabbed to death in a Lebanon home Sunday afternoon, a 31-year-old man calmly walked into the state police barracks in Colchester carrying a briefcase with a large knife in it and turned himself in, according to an arrest affidavit.

Alan Nadeau, 31, of Lebanon, told police he suffered from psychological disorders after years of sexual abuse, the affidavit said.

Nadeau was arraigned on a murder charge Monday afternoon at Superior Court in Norwich, accused in the stabbing death of Christian Beloin, 36, of Coventry.

State police said they received a call at 4:38 p.m. Sunday from a witness saying that Beloin had been stabbed in the throat at a house on Ledge Road. Police said troopers arrived at 5:08 p.m. and found Beloin lying face down in "a large pool of blood," with a stab wound in his neck. He was pronounced dead by paramedics.

At about the same time, police said Nadeau drove his car to Troop K barracks in Colchester, entered the lobby carrying a briefcase, placed his hands on his head and stated he had been abused as a child.

When detectives questioned Nadeau about the stabbing, he told them he lived with his father and his father's girlfriend in the Ledge Road home. Nadeau told police that Beloin was a friend of his father's who came to the home "often."

Nadeau told police that Beloin was sleeping next to him on a couch in the living room when Nadeau started having "flashbacks" about the earlier abuse. He told police that he went downstairs to the basement, took a bayonet from a toolbox, went back upstairs and "stabbed the victim in the face," according to the affidavit.

Nadeau told police he grabbed his computer, put the knife and computer in the briefcase and drove straight to Troop K, according to the document. Police seized the computer and the 8-inch knife from the briefcase Nadeau was carrying, the affidavit said.

Nadeau told police that he suffers from post-traumatic stress disorder and other psychological problems and that he was supposed to be taking antipsychotic and antidepressant medication, but had not taken them since last year.

Nadeau was held on $1 million bail and ordered to undergo a mental health evaluation. He is scheduled to appear again in court May 4.
